Power-on reset
The power-on detection threshold voltage is set to V
POR
= 3.5 V at room temperature.
Below this threshold, the device is reset to the power-on state.
In the power-on state, the charge pump current is set to 280
μ
A, the tuning voltage output
is disabled, the test bits T2 = 0, T1 = 0 and T0 = 1, the AGC take-over point is set to
112 dB
μ
V and the AGC current is set to the slow mode. The high band is selected by
default.
